T0 all whom t may concern.:

Be it known that I, HENRY JOSEPH ODET, a citizen of the Republic of France, and residing at Lyon, in the Republic of France, have invented certain new and useful Improvements inv Measuring-Taps, of which the following is a specification.

The invention relates to a measuring tap or valve, whereby the automatic limiting of a quantity of delivered water is assured.

It is an object of the'invention to provide a device where the intensity of the discharge decreases in proportion to its duration.

Another object of the invention is to provide a device which cannot be tampered with, which can be regulated and which leaves the hands free during the discharge of the water.

Other objects will become more apparent with reference to the accompanying drawings, the specification and the claims, forming part thereof.

Figure 1 is a sectional elevation of one form of the device made in accordance with the invention. Fig. 2 is a detail view of a partition provided in the piston. Fig. 8 is adetail view of a modification of a piston valve. Fig. 4 is a detail view of a cup. Fig. 5 is a detail sectional view of a tightening nut and rod. Figs. 6 and 7 show in inverted position detail views of the main valve. Fig. 8 is a modification of the handle. Fig. 9 is a sectional view of my preferred form. Figs. 10 to 13 show detail sectional views of still further modifications.

The device is mounted like an ordinary tap or faucet above the sink. Water-is discharged through a hollow manipulating tube or handle 1 arranged in the form of a gooseneck and capable of being swung to the right or to the left. In these movements the vertical 'portion 1a of the handle7 owing to the high pitched threads 2 formed thereon and engaging internal threadsof the neck 2a of the outer casing, rises or descends according t0A direction of rotation. A cylindrical valve 3 is secured to the part 1a and participates in the variousmovements executed by the handle.' This valve is provided with a spiral graduated slot 4 which may be brought into communication with the water inlet F. At the same time the end 44 of the portion 1zt presses against or recedes from, according to the direction of rotation of portion la, the valve 5 which closes it when a contact is formed. This valve is in the form of a facing member carried by a rotary movable head 6 1n a cup 6a on walls 7, to prevent in- ]ury to said valve by the turning of the contact ofthe handle portion la with same. The cup 6a 1 s provided with a shank 8 removably and adJustably screwed into a partition 15 formed 1n a piston 9 and said partition is formed with screw-threaded holes 11 adapted to receive check-valves, said valves being adapted to open when the piston 9 is depressed, and each valve is composed of a screw-threaded perforated plug 10a, a head 1.0, a washer 17 yand a spring 18. The partition 15 is also formed with a small hole 12 s0 as always to provide a passage for the water or other liquid and allow the piston to return. In lieu of the check valves as shown in Fig. 1, there may be used the form illustrated in Fig. `3, consisting of a single washer 17a controlling a plurality of apertures 16 in the partition 15 and springpressed'to its seat by a spring 18a acting against the adjustable head 6.

The lpiston 9 is controlled by a spring 13 and the outer end of said spring rests on a movable cup 38 adjustable by the screwthreaded shank 14 of same. The outer .circumference of the piston is grooved at 9a so as to obtain a tight iitting with the casing F1 without any packing. Owing to the small section of the opening 12 it cannot create any serious oblique factor tending to prevent the piston from returning to its normal position and when the piston is depressed, which movement can be very sudden, the valves 10 allow the water to flow' from the rear of the piston. Whatever may be the position of the handle 1, 1, if the device is considered after a period of rest the valve 5 would be raised against the end 44 and close the outlet through said handle. By turning down toward the left, for example, the portion 1a of the handle descends and pushes back the piston 9 against its spring 13 without the valve 5 ceasing to close the end 44 and the water behind the piston 9 escapes through the return valves 10. The tap or valve is thus brought into working position and is ready fordiseharging water. In order to obtain aA discharge through the neck 1, 1a it suflices to turn back `the handle portion 1 to the right. The end 44 will then separate from the end 5 because the piston 9 can only rise slowly as the water flows slowly through the hole 12, but at the same time the port 4 in the valve 3 intervenes as follows: IVhen the handle is moved back slightly to the right thus bringing the widest portion of the port 4 into register with the inlet F a large amount of water is permitted to enter from said inlet, but at the same time the end 44 is only very slightly raised above the valve 5 so that the rising of the latter very quickly effects the closing of the outlet l, 1a. vIf, on the other hand, the handle 1 is turned considerably to the right, the end 44 will be separated a greater distance from the valve 5 and the time necessary for the latter to encounter again said end will be much longer but thel slot 4 presents its narrow portion to the inlet F, thus diminishing the passage of the water.

The tap is reversible and may be constructed so that the water enters through the handle 1 and is discharged through the opening F. In this case the escape is regulated instead of the admission and it may also be arranged that the pressure of the water in the inner chamber above the partition 15 shall always be the same as that of the rising column. When the slide-valve 3 is in its closing position, it relieves the partition l5 and outlet l, l from the pressure, and generally there will be no pressure on 15 and in 1, 1a during discharge unless the channel is artificially throttled. For this purpose a screw-stud for regulating the escape is arranged at 19. The two ends of the valve 3 are perforated, as shown, to allow for the passage of the liquid.

Referring to Fig. 9, a modification is illustrated similar to Fig. l. rIhe mobility of the head 6 of the valve 5 is obtained by fitting two transverse pins 25 in an annular groove formed in a shank provided on said head. The admission of Vwater to the rear of the piston to insure its return to normal position after operation is effected through the rod 27 carried by said piston and perforated with longitudinal and transverse channel 28. The end of the rod is fitted with a thin perforated plate 29 (see Fig. 5) which is secured to said rod by means of a nut 30 and thus can be easily exchanged. A vertical channel 28 of the rod tends to retain any impurities that might clog the opening. In the detail shown in Fig. 5, a protection cone 29a is provided to further avoid the passage of impurities. In order to obtain a sliding fit between the piston and the casing, a rolling packing ring 31 of india rubber is provided around the piston 9 whose edges do not contact with the casing F1. In this manner any deformation, intentional or not, for example by outer pressure, cannot prevent reciprocation of the piston. To prevent lateral movement of the piston during its reciprocation an interior guiding sleeve is provided integral with, or screwed, or embedded in, the cap F2. The

check valves, permitting the escape of the water when the piston is driven back are arranged around the rod 27 and comprise a washer of rubber 17a controlling a plurality of'holes 16 Vprovided in the end-wall of the piston. In this modification the spring 13 acts from above and is partly inserted between double walls formed in the piston and socket 40 screwed into a housing 2a of the neck 45 of the casing, the wear7 consequently, affecting a piece that can be readily renewed. A washer 41 is provided beneath the packing 39a. The end 44 of the tube 1a is tapered downwardly at 44a and according to the length and depth of the taper presented to the inlet opening F theadmission of water is varied.

In Figs. 6 and 7, end 44 ofthe tube 1a is here formed with a number of outwardly tapered slots 44b and with'an annularV groove 44C, respectively, whereby the admission of water is controlled. A means is also provided to close the tube before it is closed automatically.' rIhetube 1a carries at its inlet end 44 a flange or shoulder b provided with a seating face of leather or india-rubber. For certain uses it may be desirable to provide a continuousstream of liquid. This is obtained by replacing the outlet cut of joint formed by the encountering of the valve 5 with the end 44 of the tube 1ZL by a peripheral valve j adapted to cooperate with a shoulder 7), b as shown Vin Fig. 7. The

movable head 6aM carrying the valve 7' is pers forated with channel c1, 01, causing its center to communicate with the exterior and with the central channel cz-in the axis of the outlet which is provided with a gage l. The continuous current may be interrupted by completely turning down the gage l.

The tap may be mounted in any position. Thus Figs. 1 and 9 show two positions the one inverse ofthe other. Since 'the discharge in Fig. 9 is centered theV outlet portion of the tube may be replaced by a solid lever 46 or retained and given the shape of a spout 47. A vsleeve 47a enables the parts 1, 46 and 46a or 47 to be fitted to the tube as desired. Y

In the modification shown in Fig. 10, a spiral slot or groove 48 is formed in which the end of an arm 49 integral with the tube 1a travels on the outside of the device as a substitute for the rapid screw threads on said tube. Y In order to provide'for the escape of the air coniined beneath the packing ring 3l holes 58 (Fig. Il) are provided in the piston 9 slightly below the end-position which the ring assumes in an upward direction; the escape of the air is instantaneous. By forming the holes 58 at the bottom of the piston the air escapes first beneath the piston 9, then through the valve,'on each operation (Fig. 12). In order to protect the ring and the calibrated opening from deposits of the liquid the piston 9 and the part-s relating thereto are arranged in a housing 6l closed at-the top and at the bottom by partitions 6ld and Glb, having two stuiing boxes through which the axial rod 27 prolonged at 59 passes so that it supports the same pressure on its extremities. The housing receives the liquid in the upper and lower chambers I and II, communicating by a hollow rib 62. A regulation of the return movement of the piston 9 can be obtained by a spring 60 in the chamber II, which spring presses against the washer 59 secured to the axial rod. The housing 61 contains a suitable liquid not ailecting either the .indiarubber or the parts employed in the apparatus, and not forming any deposits, which permits of very small calibrated openings and strong springs.

From Fig. 9 it can immediately be seen that the use of two liquids is possible without needing a special chamber for containing them. Oil, for example, occupying the casing F1 and having its level disposed beneath the cross channels 2S or, more exactly, beneath the end-position of the ring 31, will not in any way obstruct the inlets and outlets of liquid and will protect the rolling surface on said casing of the ring as well as the small liquid passages 28 from incrustation, thus assuring the slow return of the piston. 'Ihe result will be the same in the position of Fig. l with a liquid heavier than water.
